My issue is about zpk2sos conversion I presume.
The power of the numerators of second order sections are evaluated not correctly
#### Reproducing code example:

- separate realization from pole-zero placement
- realization = SVF or biquads
- not sure how to allow modulation

Dear all,
I'm developing a DSP project that need to design an IIR notch filter according to these coefficients value as coefficients array:
notch_filter_coef[0] = 0.887839755;

## 🚀 Feature
I propose make all `*_biquad` filter function become differentiable respect to their parameters (`Q`, `gain`, `central_freq`... etc.)
## Motivation
Recently there is a tr…

I attach an implementation of filters which matches ARIA near perfectly. (when implemented there)
It uses some very generic resonant filters, it showed to be quite easy to reproduce them.

Currently Stabilizer uses one biquad (IIR) per channel to realize the controller transfer function (e. g. PI). Using two biquads per channel enables us to set more complex transfer functions.
